During the week of March 16 – 20, 2009, Authorize.Net will be deprecating all legacy support for the SSL 2.0 protocol. Changes have recently been made to the Payment Card Industry Data Security Standard (PCI DSS) which have made the use of SSL 2.0 a PCI DSS violation.
Due to this change, it is critical that merchants update any applications or integrations that may be using the SSL 2.0 protocol to support the more current SSL 3.0/TLS 1.0 protocols. Failure to upgrade their applications or integrations may result in a lost ability to successfully process transactions via the Authorize.Net Payment Gateway.
Only merchants using SSL 2.0 to connect to the payment gateway will be affected. If you are currently using SSL 2.0, you must contact your Web developer immediately to arrange to update integrations to the SSL 3.0/TLS 1.0 protocols.
It is critical that Authorize.net merchants contact their developer immediately to verify whether their integration will be impacted.
